Tertiary sediments

In the Ural-Sakmara basin, total Cu is 60-70 mg/kg in chernozems on secondary sediments. Chestnut soils on weathered basic rocks in the Or-Kumak basin contain higher Cu (88-96 mg/kg). The average Pb concentrations are 11-25 mg/kg in chernozems derived from serpentinite and secondary/tertiary sediments of the Ural-Sakmara basin. Soils in the Ural-Sakmara basin on serpentinite contain 133 mg/kg total Ni. [Pg.62]

The studied springs discharge from almost all of the geological formations within the State of Sao Paulo, from the crystalline rocks to the sediments of the Parana Basin (Fig. 1). Most of the springs, 43 in number, are from the magmatic and metamorphic rocks of the Crystalline Complex, nine from the sediments of the ParamA Basin, and one spring is in Tertiary sediments of the... [Pg.25]

The Cretaceous sediments consist of evaporites, limestones, dolomites and thin sandstone beds. The calcareous littoral facies of the Apt and Alb are oil-bearing in Tunisia and sandstones of the same age represent the main aquifer of the northern Sahara. The subsequent Tertiary sedimentation in Tunisia led to great thicknesses of up to 7 000 m. These sediments represent the succession from the Paleocene to Pliocene in the east and in the littoral parts of the Gulf of Gabes in Tunisia. The Alpine orogeny of the Tertiary raised the unstable parts of the platform and resulted in a multitude of faults and other complex structures. [Pg.17]

The Middle Jurassic and younger section on the stable Saharan Platform is dominated by relatively thin lagoonal dolomites, evaporates, and shales. Cretaceous sediments consist of alternating evaporates, limestones, dolomites, and thin layers of sandstone. Aptian-Albian nearshore carbonate facies are oU-bearing in Tunisia. Tertiary sedimentation is particularly present in Tunisia and farther over a wide scale of thickness (up to 7000 m). These sediments occvn from the Paleocene to the Pliocene in the east, and... [Pg.239]

In 1995, Japan s Ministry of Economy, Trade and Industry (METI), formerly Ministry of International Trade and Industry (MITI), launched a project to explore for marine gas hydrate accumulations around Japan. From late 1999 to early 2000, an exploratory hole MITI Nankai Trough was drilled on the landward side of the eastern Nankai Trough, offshore Japan (Fig. 1) by Japan National Oil Corporation (JNOC) along with Japan Petroleum Exploration Co., Ltd (JAPEX) as the well operator. The water depth at the drill site was 945 m and the sub-bottom depth of the hole was 2355 m. The seismic bottom simulating reflector (BSR) is present at around 295 mbsf. There were two exploration objectives one was a gas hydrate survey in shallow Quaternary sediments and the other was conventional oil and gas exploration in deeper Tertiary sediments. In addition to the main hole, seven short holes (two site survey, two pilot and three post-survey holes) were also drilled for the gas hydrate survey around the main hole. In this paper, we will clarify the origins of methane in gas hydrates found in the MITI Nankai Trough Well and discuss gas migration and hydrate formation in the sediments. [Pg.377]

In sandstone from the river Nionzi-Lubunzi in Lower Congo, Vanderstappen and CORMIL [1958] have found what they consider to be a complicated interstratification of mica, hydromica, and montmorillonite in equal proportions. Kobayashi and Oinuma [1961] have found random mixed-layer minerals together with montmorillonite, chlorite, and illite in tertiary sediments of the Chichibu basin of Saitama Prefecture, Japan. [Pg.286]
